This invention resides substantially in the combination, construction,arrangement, and relative location of parts, all in accordance with thedisclosure herein.

Figure 6 is another modified embodiment of this invention.

Figure 7 is a section on the line 1-1 Figure 6.

The true nature and manner of use of a device in accordance with thisinvention will be best understood by a detailed description of the formthereof shown in the drawings in an illustrative sense.

A preferred form in accordance with this invention includes parallelmain electrodes 2 and 3 longitudinally extended between opposite members4 and 5; spaced by one or more spacing means comprising a wire member bone end of which is in fixed engagement with main electrode 2 theopposite end being wrapped around the outer periphery of the insulatingmember 0 thru which main electrode 3 passes; insulated therefrom bysuitable insulating members 6 and being in contact with a source ofelectric current thru conductors l and 8 either directly or thruatransformer depending upon the desired voltage.

Suspended from said main longitudinal electrodes 2 and 3 are a series ofvertical tap electrodes 9 and [0 which may be hooked to the invention topro- 1 in close proiiiih'itytb' or contact with the elec allychalrgedele ems; b'y'iwhicl'i they are e1 un ut-ea, wur fall clear or theelements i s' and" notfclogor obstruct the'l pace" theelbtfdds anuipossisiecaus ng of a' a clogging around the top rim of the insulatorvention is to with; secured I means of solder, or in any othersuitabllbr ventional-ma-nherj i i 0bservation-- of Figures 1 and 2teachesthat roarsm nszed preue terminedispace as tocachother "by meaneonw'ire said tap electrodes 9 and spacing; members Hf which is in: fixedengage ment with the electrode 9 in a manner such 'as abovedCSGll'bEdrfOIrlihG" engagement: of thee tap electrodesw ith thermainelectrodes the opposite end thereof circumscribings the outer. peripheryt e l in m r h (W ich th electrodelllfpasses and wh e in the drawingonly a single: spacing means is shown for each pair of electrodes, it isobvious of the tap electrodes should demand additional spacers samecould be. supplied without impairing the spirit of the invention.

As herein pointed out an object of this inprovide a device of thecharacter here described whereby the carcass of the insect will fallclear of the electrodes and especially is this true in the structureabove described, wherein the path between any pair of electrodes isnormally so close that the additional thickness of the insulator [2would tend toward causing l2 thereby obstructing the path between theelectrodes, and possible shorting of the circuit, therefore to overcomethis possible condition the electrode 9 is indented at I4 from abovethetop of said insulator l2 thus permitting any carcass to pass same andfallclear of the elements.

Now referring to Figures 3, 4, and 5, which illustrate a modified formof structure it will be observed that in the main the structure iscomposed of two gratings l5 and I6 which are embodied Within a frame [1,in insulated fixed engagement therewith at the four corners thereof thruinsulating members l8. Each of these gratings comprise an assembly ofgrids in the form of parallel vertical electrodes I9 and 20 which may betermed main electrodes, and a series of parallel horizontal tapelectrodes 2| and 22 which are respectively connected in unitary circuitassembly by solder connection, splicing, or other conventionalconnecting means, however, observation of Figure 4 will teach that ifboth vertical electrodes were run in contact with their respectivehorizontal electrodes in their normal plane, said vertical electrodeswould be so close that the insect carcasses would readily clog andobstruct any passage therebetween, therefore to assure a clear passagethe horizontal electrodes eietroues anupresseumr contactthere: therewithby end turns; joinedfby that, if the length 22 are indented at 24 andthe vertical electrode 20 run within the space thus provided.

In this structure it is thought best to make contact with a source ofelectricity thru the vertical electrodes, and as indicated thrurepresented conductors 25 and 26.

Figures 6 and '7 illustrate a further modified form of structure whereinthere is a double set of triangular gratings 30 and 3| in the form ofvertical grids orelectrodes 32 and;33 in circuit contact withparallelhorizontal electrodes 34 and 35 respectively.

Similar to other forms of structure herein described, it is necessarythat the structure be so formed that the passage between oppositevertisire to be strictly limited by the disclosure but rather by theclaims granted me.

What is claimed is: r

l. A device of the kind described, comprising a normally open electricalcharging circuit, and including independent groups of fretwork-likecontacts spaced from each other for clearances between such groups andthe contacts thereof, closing of said circuit being efiected byengagement of aninsect withzcontacts of both groups thereof. T r

2. A device of the kind described, comprising i .a;normally openelectrical charging circuit, in-

I eluding independent tacts spaced from each other for clearances becalelectrodes be kept clear, to this endthe apex terminals of the grating3| is receded in a manner as shown at 36 and thevertical electrode -33run within the space thus provided.

As previously pointed out, it is desired, although not compulsory inanyfform of structure, that electrical contact shall 7 be) made verticalelectrodes.

In thismodified structure there i s shownl an electric lighting means,however this is a well known means for attracting insects and no claimis made to this individual item, same being shown toillustrate, onemanner of using this particular structure.

:fFrom the above description it willbe apparent to-those skilled in theart that the-details ofconstruction illustrated-herein may readily bevaried without departure from thenovel subjectmatter herein disclosed. Idonot therefore, de

closing of said circuit being effected by engagemerit of an" insect withthe contacts of both groupsthereof, and insulating means holding the grups of contacts in their spaced relation to each other/for minimizinginsect clogging of the 3. A device of the kind described, comprising anormally open electrical charging circuit, fin-Q eluding independentgroups of'bar-like contacts spaced from each other for clearancesbetween such groups and the contacts thereof, the closing of saidcircuit being effected by engagement of an insect with the contacts ofboth groups thereof, insulating means holding the groups of contacts intheir spaced relation to each other for minimizing insect clogging ofthe clearances, and means for supporting said groups'of "contacts andthe insulating means assembled.
